PLATE-SINKING DIE.

Application filed October 20, 1925. Serial No. 63,777.

My invention consists of an improved plate sinking die, the object of which is to provide a simple and economical device for use in embossing cards, photographs and the I like.

In the accompanying drawing illustrating my invention, F ig. l is a plan view, and Fig. 2 a vertical transverse ysection on line X-X of Fig. l.

Referring to the drawing, 3 is a thin sheet ot' material, preferably Celluloid, although glass or any other transparent material will be suitable for the purpose. The sheet 3 ot transparent material is secured at one edge to a rectangular trame 6 made of a thin sheet ot cardboard, or any other suitable material. A rectangular opening 4,

shown in dotted lines, is cut out of the :trame 6. Secured to the under side of the trans- !.0 parent sheet 3 is a sheet 7 ot transparent material, preferably made ot Celluloid or of the same material as the transparent sheet 3.

The sheets 7 and 3 may be secured together by lacquer or any cement that does not inter- :tere with the transparency of the two sheets.

The sheet 7 is ot the same size as the opening 4 in the :trame 6 and tits snugly therein when the sheet 3 lies in close contact with the frame 6, allowing space to accommodate the thickness of the paper. 5, 5 are eyelets by which the sheet 3 and the trame 6 are secured together at one end, but by reason of the elasticity or' the materials or' which the sheet 3 and the traine 6 are made, they are 85 readily separable throughout the remainder ot their length so that a photograph or other card to be embossed may be inserted between them. While I prefer to eyelet the sheet 3 and frame 6 together, other means, of

40 course, may be used for connecting them without departing trom my invention.

ln operating the device ot my invention,

a card to be embossed having been inserted between the sheet 3 and :trame 6, sutlicient pressure by a hand or power press is applied to force the sheet 7 down into the space t in the frame 6, and thereby to sink the photograph or other card with it into that space, and thereby form a raised mar-V gin around the photograph or card to give an attractive effect.

It is obvious that the opening t in the trame 6 may be made circular, oval or of any desired shape, and ot course, the sheet 7 must correspond in size and shape thereto. 55

The advantages of my invention are that kthe plate sinking sheet being transparent,

the picture or print upon the paper to be embossed is visible at all times, and can be accurately centered, and is securely held in correct position between the sheet 3 and the frame 6 so that it cannotv slip and become displaced during the operation oi' embossing. lt is also inexpensive to make and easy and simple to use.

lfVhat l claim and desire to secure by Letters Patent is;

A plate sinking die comprising a frame having a die opening therein, a carrier sheet overlying the front face of said frame and extending over said opening, means uniting the carrier sheet and frame at one end so that they may be separated at the other end, and a die block secured to the back of said carrier sheet in a position to be normally maintained in vsaid opening by said sheet, so that when a piece ot' work is interposed between the trame and the carrier sheet, it may be embossed by said die block upon the application thereto 'of extraneous pressure, 80 said die block and carrier sheet being transparent so that the work may be visible to the operator while being placed in position between the carrier sheet and the frame.

In testimony whereof l have hereunto set my hand this thirtieth day ot September,

JOSEPH R. THONET.
